Republican presidential nominee Donald Trump has railed against immigrants on the campaign trail, even though, according to a new report, his own modeling agency profited from illegal foreign labor.

Donald Trump's modeling company was a “crooked agency” that put young women into “modern-day slavery” and had them working in the U.S. illegally, former models for the organization claimed in a bombshell report published Tuesday.

Trump Model Management, which was founded by the GOP nominee in 1999, has made its money on foreign models working in the U.S. illegally and under horrible conditions, several former models told Mother Jones magazine.

“Honestly, they are the most crooked agency I’ve ever worked for,” said Rachel Blais, a Canadian-born model who signed with Trump Model Management in 2004 and worked for the company without the proper visa paperwork.

Another woman, identified by the magazine as “Kate,” who said the agency never obtained a work visa for her even though she worked for them as a model in the U.S., blasted the mogul for his apparent hypocrisy.

Trump profited from foreign labor, and often illegal workers, while the GOP nominee on the campaign trail bashed immigrants and threatened to “round up” 11 million undocumented immigrants with a “deportation force.”

“He doesn’t like the face of a Mexican or a Muslim,” Kate said, referencing Trump’s proposals to ban all Muslims and to build a wall along the border. “But because these models are beautiful girls, it’s OK? He’s such a hypocrite.

“He doesn’t want to let anyone into the U.S. anymore,” she said. “Meanwhile, behind everyone’s back, he’s bringing in all of these girls from all over the world and they’re working illegally.”

Another model identified as “Anna,” for whom the company also didn’t obtain a work visa, ripped Trump, who to this day holds an 85% stake in the company, for the anxiety the lapse caused.

“I was pretty on edge most of the time I was there,” she said. “I was there illegally...a sitting duck,” said Anna, who added that the agency even instructed the models not to be truthful with customs officers at airports.

“If they ask you any questions, you’re just here for meetings,” she claimed she was told.

Foreign visitors are prohibited from working in the U.S. unless they have one of a handful of types of work visas, which are usually obtained by the employer. It is also illegal for foreign visitors to work in the U.S. while in the country on a tourist visa.

The allegations come just weeks after questions emerged about the past immigration status of Trump’s own wife, Melania.

Ironically, the type of work visa that would have allowed the women interviewed by Mother Jones to work here legally — an umbrella of visas known as H-1B — would be scrapped entirely under a Trump presidency.

“I will end forever the use of the H-1B as a cheap labor program, and institute an absolute requirement to hire American workers for every visa and immigration program. No exceptions,” Trump said in a March 3 statement still on his campaign website.

Trump also made his illegal models live in unfathomable conditions, the report claimed.

The women interviewed by Mother Jones described arriving in New York City and being forced to share a crowded basement apartment in the East Village.

The two-bedroom apartment, which Blais said was rented to the women at inflated prices, was at times occupied by more than 11 people, with bunk beds packed into every room.

“It is like modern-day slavery,” Blais said, adding that “most of the girls in the apartment that were not American didn’t have a work visa.”

“We’re hoarded into these small spaces,” Kate recalled. “The apartment was like a sweatshop.”

“I was by far the oldest in the house at the ripe old age of 18,” Anna added.

A spokeswoman for the Trump campaign didn’t respond to questions about the allegations. A spokeswoman for the Trump Organization, the umbrella company for all of the mogul’s enterprises, did not respond to questions either.

The claims come just weeks after questions emerged about the past immigration status of Trump’s wife, Melania, who may have once been an undocumented worker who illegally made a living in this country.

The Slovenian-born Trump has repeatedly said she first came to the United States in 1996 as a tourist on a short-term visa — a year after newly released erotic photos were taken. But those documents wouldn’t have allowed her to legally work in the United States as a model.
